Hiron®+ Tridur® Finish 300 +Zintek® Top Black S
Deep piano black appearance, with outstanding corrosion protection properties
Our superior black coating system combines a black passivated Hiron layer, a high-performance zinc iron alloy free of nickel or other heavy metals, with an intermediate layer of Tridur Finish 300, a chromium(III) based post-dip, covered by Zintek Top Black S, an inorganic black silica-based topcoat with delayed corrosion behavior. The result is a deep piano black appearance, with outstanding corrosion protection properties of more than 1,000 h without base material corrosion. The topcoat is also available with lubricant for controlled friction properties.

Features and benefits
- The combined solution of plating and zinc flake technology with reactive sealing properties achieves superior corrosion protection.
- The Hiron zinc iron alloy with 12 – 16% iron incorporation is free of nickel and toxic material. It does not exhibit any cyanide formation and provides a homogenous thickness.
- Tridur Finish 300 is a Cr(III)-based post-dip or intermediate layer that enhances the black appearance and scratch resistance and gives additional corrosion protection.
- Zintek Top Black S is a black solvent-based inorganic topcoat with a unique piano black appearance and delayed white rust formation.
